Can you tell me something about the suggested retail price of the game and when will it be available to buy ?

The game will probably become available around summer. Most likely at June but there is a chance it may get delayed for July or even August. As for the price it will be available, we will know for sure during April but it will probably be somewhere around 20€, maybe even less.

Are there a lot of boardgamers in Greece ? Is that community strong and well connected, with associations or gaming groups?

In the last years the greek boardgame players have increased a lot. One of the reasons has been the translation and publication by Kaissa Chess & Games of many popular board games in greek, attracting this way many new players to the hobby. One other reason has been the creation of the Greek Guild in boardgamegeek. It has been active for almost 4 years now and it is one of the most active guilds on the site (if not the single most active guild). The best thing that it has helped with is that it has brought all the greek boardgame players together. We have formed a community, sharing reviews, opinions, strategy tips etc and we have now reached the point where we regularly host meetings to play boardgames and get to know each other. Out of these meetings new friendships have been made and new games are constantly introduced to more people. The last two years we even had two boardgame design contests. You can read about the second one here: http://www.boardgamegeek.com/blogpost/1155/greek-guilds-2nd-boardgame-design-contest

How did you thnink to become a game designer ? Can you tell us something about your experience ?

Many years ago I was a Magic: The Gathering player. I used to read articles about strategy, deck-building and draft advices. However, I also loved to read Mark Rosewater's articles (the lead designer for Magic) which were about the design process behind the game. I was fascinated by them and I found all the information they provided extremely interesting. After a few years I quit Magic and I got into boardgames (around 5 years ago). Even from the start I remember that I had thoughts in my mind about designing my own game. At first I didn't pay a lot of attention to these thoughts, dismissing the idea as something that was not ever going to happen. However I was still interested in reading articles from game designers who were explaining how they got their ideas, what they changed to make their games work and so on. At some point, the idea for the game Souvlaki Wars started forming in my mind. I decided to explore that idea and see if I could design a game myself. The rest as they say... is history!
The whole experience with the design of Souvlaki Wars really opened a whole new world to me. Right now I am constantly thinking of new game ideas and my only problem is that I don't have enough time to explore all of them. I have decided that I want to keep designing board games and I would love if I could some day make it my "day job". Not because I want to make a lot of money out of it, but because it is something I really love and enjoy and I want to dedicate as much time to it as possible.
